I asked my husband's permission to share this story... It's a perfect example of how our two year old daughter parrots the things she hears, even feigning the wisdom behind the words:
One day, my husband was walking in the woods with my daughter when some gas escaped him, as it is wont to do. It must have been fairly voluminous and noisy, because my daughter wisely followed a philosophy we've developed regarding her dangerous sounding flatulence:
"Daddy! You farted... Check your diaper."
That's my girl. Taking care of her daddy already.
